fu Improvements in Spraying Heads or Nozzles, of which the following is aspecifi- 7 cation. 1

This invention relates to spraying heads, or nozzles, such as are especially adapted for I use in connection with a street flushing or comparatively vfree and unobstructedfflow sprinkling machine.

The device is particularly an improvement I on the spraying head shown in the U. S.

' 4., 1911. The present improvement relates particupatent to Jackson No. 996,767 dated July larly to the structure of the casing containing the turning or rotary plug valve, and is intended to provide a better supply of water to the nozzle, so as to give a clear and unobstructed stream of maximum efliciency and even distribution, avoiding what isknown of water in". the spraying as pocketing head.

The invention will be more clearly understood from the following description and the accompanying drawings in which- Figure 1. is a side view of the head or nozzle. Fig.2 is a front or face view. Fig. 3 is a section on the line 3-3 of Fig. 1.

Referring specifically to the drawings, 9 indicates a tapered tubular casing provided on one side with the inlet connection 12 and on the other side with an outlet mouth or slot 7 which extends lengthwise almost the whole length of the casing and has projecting lips as shown. Fitting within this-casing is a tapered plug 6, which can be turned to open or close the discharge outlet. This plug has extending across the same a converging passage 8. In the patent above referred to the passage 8 is flared from a circular opening at the middle, where the inlet connection joins, to a narrow outlet slot at the opposite side, corresponding to the mouth 7 and the inlet connection 12 is also circular.

- the outlet side.

middle circular opening, but extends substantially the same shape throughout its whole length. That is, the passage through or flared neck;13.- :Gonsequently the water spreads before it enters the plug,-instead of being spread within the plug, as in the patcut above referred to, and the water hasa through the passage in the plug. This has been ound to give a better distribution and a more effective discharge than the structure a ,v

in the patent above referred to.

The other parts are not substantially changed, that is, the plug is provided with a nut 11 at the small end and a gasket 10 at the large'end, and the stem of the plug is squared as at 14 to receive an operating lever or device.

With respect to the action of the head, water which enters the same through the inlet 12 will spread laterally in the triangular or flared neck 13 and will then be discharged through the cross-passage 8, flowing in a sheet through the mouth 7 when the head-is fully opened. By turning the plug along the full length of the plug, the supply is substantially uniform along the full length of the mouth,'in all open positions of the What I claim as new isi A spraying head comprising an elongated casing having a discharge slot extending lengthwise on one-side thereof, and a water inlet neck flattened and broadened laterally and extending lengthwise along the opposite side of the casing, and a turning plug in the casing, having a cross passage the walls of which converge in a plane transverse to In testimony WheI eof, I affix my signature the axis of the plug, the passage belng sub in presence of tWo witnesses.
